Dear PSB,
There is indeed an issue, and it is unavoidable, because we are using default views for List and Document Libraries in Related Items. It's caused by the presence of RootFolder parameter in URL, as it is not interpreted correctly in this case. But even though the issue is unavoidable, there is a workaround - it's possible to use the main form for redirection, and while redirecting, remove RootFolder parameter from the URL.

First of all, you need to create a new Form Set to place Related Items on. Create a Form Set and set rules to something that will never happen, like:

Code: Select all

1=-1

FormSetWithRules.png (16.66 KiB) Viewed 2140 times

This will ensure that users are only redirected here manually.

Next, export the main form and import it to this new Form Set, so it's fully usable:

ExportImport.png (11.42 KiB) Viewed 2140 times

Go back to main form and delete everything! This form will only be used for redirection to Form Set.

After deleting everything, you will need Form Set's ID / page name, so go back to the form that you've configured and copy it:

FormSetFormName.png (6.41 KiB) Viewed 2140 times

Then, go back to the Main Form and add the following code to redirect users to your Form Set and remove RootFolder property in the process (use form name here):

Code: Select all

var uri = fd.setUrlParam(decodeURIComponent(window.location.href), 'FDRedirectWithID', 'fd_Document_4b469244-cc60-47fd-9cdc-f9c3283a05aa_Display.aspx?ID=');
fd.openForm(uri, {RootFolder: ''});

This should work! In the end, you will have an empty main form with JS to redirect users to a form set, and form set can have Related Items Tasks List and it would function properly.

Now, this solution is cumbersome, but there is no workaround, as it's one SharePoint quirks with how interprets data in URL, this is just a way to avoid it entirely.
